OpenEBS is a Stateful Persistent block-mode Data Storage platform with an native vSAN fabric; for Kubernetes. We are CNCF member project. We are the largest global community of K8s storage users.
Our project team was an early pioneering inventor of K8s Container Native Storage services (we invented the term). We conceived the vision of a Stateful Persistent data platform for K8s that is tightly integrated and natively embeded into the core of K8s.
We built an innovative High-performance Enterprise grade Block-mode Hyper-converged Storage vSAN Fabric that augments the storage services of K8s with Stateful Persistence, Enterprise Data mgmt, SSD/NVMe optimized I/O services, Replicated Data volumes, Thin Provisioning, Snapshot, Clones; and many other Mission critical data storage services that don't come
in K8s out-of-the-box.
OpenEBS is very popular :
Live OpenEBS systems actively report back product telemetry each day, to our Global Analytics system (unless disabled by the user).
Below are our project popularity & pentration metrics as of: 01 May 2024🚀 OpenEBS is the #1 deployed Storage
Platform
for Kubernetes
⭐ We are the #1 GitHub Star ranked K8s Data Storage platform
💾 We have +49 Million Volumes deployed globally
📺 We have +9 Million Global Live Nodes
⚡ 1 Million OpenEBS K8s Containers arespawned per week
😎 1.7 MillionUser Installations

Building a K8s Enterprise Data Storage platform is complex, and areas of the Data & I/O stack could be considerd 'Storage Rocket science'. Our global team comes from many areas of the data storage industry. Companies like... Microsoft Azure, VMware, DELL/EMC, Brocade/Broadcom, Hitachi Vantara, INTEL, Nvidia/Mellanox, IBM, RedHat and DataCore. |

We are an Ultra modern Data storage platform stack that is strongly aligned with the cutting edge direction of storage use-cases in the K8s industry. openEBS is designed to facilitate modern K8s datastore architectures, key K8s I/O patterns, K8s data access methods, K8s data use-cases and where K8s Datastore applications are heading.
OpenEBS is optimized for NVMe and SSD Flash storage media, and integrates ultra modern cutting-edge high performance storage technologies at its core.
☑️ It uses the High performance SPDK storage stack - (SPDK is an open-source NVMe project initiated by INTEL)
☑️ The hyper modern IO_Uring Linux Kernel Async polling-mode I/O Interface - (fastest kernel I/O mode possible)
☑️ Native abilities for RDMA and Zero-Copy I/O
☑️ NVMe-oF TCP Block storage Hyper-converged data fabric
☑️ Block layer volume replication
☑️ Logical volumes and Diskpool based data managment
☑️ a Native high performance Blobstore
☑️ Native Block layer Thin provisioning
☑️ Native Block layer Snapshots and Clones
LEGACY consists of Data-Engines that we experimented with early on. These Data-Engines have a number of open-source
technologies embedded inside them, and are a great intro into the world of simple K8s storage services. LEGACY helped
us learn, iterate and develop our core storage K8s strategy, as well as discern how users want & need to interact with
K8s storage services. LEGACY also helped to reveal key areas within K8s that are lacking in storage/datastore services,
what areas of K8s we could optimize; and how we can provide the best value into the various K8s storage layers.
There are multiple Storage Engines within LEGACY:

Our 2024 Roadmap is here It defines a rich set of new features that are planned for 2024.
Please review this roadmap and feel free to pass back any feedback on it, as well as recommend and suggest new ideas. We welcome all of your feedback.
OpenEBS is the most successful Stateful Persistent Container Native Storage platform in the CNCF landscape. It has always held the #1 position and continues to as of today.
Important
Our orignal founding team guides the project as Maintainers. Major sponsorship is provided by DataCore, who donates a large team of dedicated Product Dev/Engineers, Product Mgmt and operational rescources. OpenEBS has 100's of amazing contributors and storage engineers who provide ideas, feedback, and high-quality code to the project. - Everyone is welcome.
The community meetings are usually held monthly on the last thursday of the month at 14:00 UTC.
The meeting is currently held on google meet: https://meet.google.com/oaa-fycu-vsq
